Some recent listener feedback

Hi guys,
Just a heads up, I find your appraisals are not consistent 😜
Take for instance the "oooooh" and "arrrrr" for Tamron's lodged patent for a 115mm 1.4f lens, now if I remember, I mentioned Nikon's 105mm 1.4 some episodes back, and the fanfare was like, "I yeah, not that much into bokeh or words to that effect.
Well at least you can walk into a shop right now and purchase it, it's not just on the drawing board. Anyway I had my grumpy old man rant for the day.
Keep the pods coming😊
Cheers Carl
Wow, made the podcast again.
I really enjoyed the Landscape photographer of the year book. It has great photos of the English countryside along with a short story of how the photo was made and the camera settings. It was helpful for me to see what kind of photos were chosen as the winners.
Have a good one, Bruce, love the show.

Hi guys, another interesting podcast.
Very surprised and disappointed to hear Glynn's info about the liquidation of L&P. They are just near my home and I recently bought a Tenba messenger bag from them. I concur with Glynn's comments about their bags, they are very well designed and well made. Another great photography store lost to us.
Keep up the great work,
Peter Sambell

This week, David Marland joins me in Glynn’s absence.
Rob Coates sent us this link to some of the Wildlife Photographer of the Year images for 2017,
and this story about an Australian couple whose raunchy wedding photo got ALL foreigners banned from shooting at a monestary in Greece.

This one is quite time-sensitive. Book publisher, Rocky Nook is donating all profits of book sales to victims of the recent (October 2017) Northern California bushfires.
Offer ends Oct 29.

Lee Filters has announced reverse ND filters for sunrises and sunsets.
In the podcast, I mentioned Hoya as a brand I thought might have been in the market earlier, but a quick search on Google would suggest a number of other players. Formatt HiTech, Singh Ray, NISI, etc

Glynn is also mightily impressed by iPhone’s new portrait stage lighting.
The first image is how the room lighting looked.
The second shows the iPhone’s fairly decent effort at isolating Barbie from her background.

And Glynn bought himself a new camera!
A new top-of-the-line pro D-SLR?
Heck no!
A Yashica Y35!

Also, Canikon users might be interested in Pulse, a devise for doing all kinds of funky triggering and remote work with your DSLR.

And Steve Peters suggested that Glynn should check out “Can I Fly There?“, a document produced by Australia’s CASA (Civil Aviation Safety Authority) on where you can and cannot fly your drone UAV.
Glynn affirmed that he had already done so. Good stuff!

Hi Bruce,
I’m a long (long) time listener and I just finished listening to episode 384 (the Reg Vardy one).

You talked about a method of computing long exposure times by setting the ISO to 6400, measuring exposure, and then setting the ISO to 100 and exposing for minutes instead of seconds. You said that the system does not work because there are 7 stops between ISO 100 and ISO 6400, and you were using a 10-stop filter.

Well, there are 6 stops between those ISOs (2^6 = 64). And that method does work – it’s just that you need to use ISO 6400 and ISO 100 under the same conditions. In other words, if your measured exposure time at ISO 6400 was 5 seconds with the ND filter on, then it will be 5 minutes at ISO 100, again with the ND filter.
If it was 0.5 seconds without the ND filter at ISO 6400, then it will be 30 seconds at ISO 100, again, without the ND filter. The ND filter only changes the exposure times, not the ratio between them.

Using ISO 6400 enables you to quickly gauge exposure (using the histogram), white balance, exposure, focus, etc., before committing to a very long exposure at ISO 100.

Note that with a 10-stop ND filter the exposure time difference is likely to be x120, not x60, because at ISO 100 the exposure time will probably be longer than 1s, triggering dark frame subtraction which takes the same time as your exposure.
